Watch and Ward [EPUB ebook] 

Wealthy Roger Lawrence adopts twelve-year-old Nora Lambert after her father kills himself in the hotel room next to Lawrence’s. Roger had refused financial assistance to the man, and he feels remorse. Nora is not a pretty child but she soon starts to develop, as does Roger’s idea of eventually marrying her.
Unfortunately for Roger, once Nora matures into a beautiful young woman, she is attracted to two other men: worthless George Fenton and the somewhat hypocritical minister, Hubert Lawrence (Roger’s cousin).
After various adventures Nora winds up in the clutches of Fenton in New York…
A poignant story of unfulfilled lives and lost love.
